Thanks John.

I should explain that I have only MPC8548 on the board. Other elements with access via RapidIO will be on another board which is not connected now. I guess that the common transport size does not matter in this case because we do not have any communication.

Should I assume that the most probable reason of hung up i the mapping of memory? The kernel hung up in function in_be32(regs_win + RIO_CCSR). This is access to configuration register.

Thanks, Adam

Adam,

Make sure you have matching common transport sizes in your system -

Section 4.4.3.16 RapidIO System Size in the 8548 manual.
